@flohack Hey thanks for the reply. I attempted to wipe all partitions with TWRP, and formatted data as ext4, but I'm still hanging at Mounting Partitions. Anything else I can try? I could probably find a Windows computer to try to install from, but I suspect that is not going to be a solve. What is ubports-installer doing under the hood at the "mounting partitions" step? Is there a way I can attempt that step manually to get more verbose output?

Thanks again.

Hey there, this seems to be the same issues I'm having, as well, so I figured posting here would be better than starting a new thread. I've been fighting with this for a couple nights now, but I'm not getting anywhere. I've flashed PQ3A.190801.002 via the chrome WebUSB flash link for the Factory Image (not OTA), attempted the 0.8.9-beta snap and the 0.9.1-beta AUR install, run the snap install with sudo, etc... Still getting the same behavior. It hangs at "Mounting Partitions..."

Any idea what I might be able to do to get past this?

I'm happy to attach my log file or send it where I need to, please just let me know the best route for that. I don't seem to be able to attach it here as a file, and copy/pasting the whole log seems like bad form? Happy to be told I'm wrong on that, though. Here's the last 10 lines, at least:

{"level":"info","message":"Downloaded file 8 of 12"}
{"level":"info","message":"Downloaded file 9 of 12"}
{"level":"info","message":"Downloaded file 10 of 12"}
{"level":"info","message":"Downloaded file 11 of 12"}

Thanks in advance!
